Introduction

The above image has been color corrected and blurred in photoshop to create the depth of field effect. This tutorial will be focusing on the dirtmap material which is included in vray version 1.5. I always like to use this material in my renders to add a little more realism. You need a basic knowledge of 3ds Max and vray to complete the tutorial.

Setting up the shader

Download the support files from here supportFilesDirtmap.zip

Load the scene file and create a new Vray matarial

Assign the material to the building walls (i have grouped the walls of the front building so the windows are seperate)

Add the VrayDirt shader to the diffuse slot

The default options are displayed for the dirt material Map a bitmap file texture to the radius slot and link the supplied dirt.jpeg
